Who is FBI Director Christopher Wray?

FBI Director Christopher Wray is facing renewed criticism after reports surfaced that the bureau did not act on a recent tip about Florida shooting suspect Nikolas Cruz prior to the massacre at Marjory Stoneman Douglas High School in Parkland on Feb. 14.

In a statement, the FBI admitted to receiving a call on Jan. 5 from a person close to Cruz who contacted the FBI through its Public Access Line (PAL) tipline to express concerns about his erratic behavior, disturbing social media posts and his desire to “kill people.”

“Seventeen innocent people are dead and acknowledging a mistake isn’t going to cut it,” Scott said in a statement. “An apology will never bring these 17 Floridians back to life.”

Officials encourage the public to “see something, say something,” Scott continued, but in this case, the “FBI failed to act.”

“People must have confidence in the follow-through from law enforcement,” he added. “The FBI Director needs to resign.”

After learning the FBI had been warned about Cruz, Attorney General Jeff Sessions ordered an "immediate review" of both the Department of Justice and FBI’s practices.

“It is now clear that the warning signs were there and tips to the FBI were missed," Sessions said in a statement. "We see the tragic consequences of those failures."

Wray said the bureau would also review what had happened.

“We are still investigating the facts. I am committed to getting to the bottom of what happened in this particular matter, as well as reviewing our processes for responding to information that we receive from the public," Wray said in the statement. "When members of the public contact us with concerns, we must act properly and quickly."
